If I was in your shoes I would look at the Edelbrock (
www.edelbrock.com )performance packages. They include the cam, intake, heads, and carb. They are proven combinations that work well. Look at the Performer and Performer RPM...following the basic engine buildup then look at headers, ignition, cooling, fuel delivery, and maybe a Dr.gas "X" pipe with a 2 1/2 inch exhaust. Lots of airflow thru the motor.
Pretty basic stuff..youre in Bellevue I see...Just a bit south of you in Vancouver, WA
